Introduction
Common Evolution Magic Tricks Exposed

* Man did not decend from the ape
* Godzilla can not evolve from nuclear waste
* Neither Apes nor Primates can (again) evolve to the smarts of The Planet Of The Apes
* humans can not grow new arms from nuclear waste as in planet of the apes 17, and Total Recall
* Even Science Fiction can hardly read the genes of two living dinosaurs from the gene map of just one.

Hollywood,
markets mutations as the tiny little gene sourcerers of Nature.

It is not clear whether the film makers are ignorant,
or are just greedily uneducational.

Replication
A replicator is a creature that can make copies,
or replications of itself.

When a woman bears a child, he is similar in charachter
to his mother and father: he is human.

Humans are replicators.

When a replicator makes a copy of itself,
there are now two of them.

Next time, both will replicated and there will be 4.

Next time, there will be 8.

Next time 16.

At the tenth time, 1024.

At the 20th time, about a million.

At the 30th time, a billion.

If adam and eve bore four children, doubling
their quantity, and so on with each generation,
there would be a billion people on earth
in thirty generations.

The Cockroach female,
in her lifetime, will lay up to a million eggs,
in some cockroach species.

Try to imagine this:

One female cockroach would live and die in about one year,
leaving a million cockroches.

Each of the half a million females will do the same next year,
leaving 500 billion cockroaches around.

Next year there will be more.


In The Origin Of Species,
Charles Darwin gives a long and detailed
account of how quickly different animals in Nature would grow
to cover the earth.

Seventy Cheetahs In A Territory
The territory is an ecosystem.

It is supplied and is being discarded of
steady and predicatable resources.


Let us say it is just light from the sun, water, and minerals.

In Nature, this is never really so simple.

But usually there are territories that are sort of separate
where things don't change so much most of time.

In Science, we look at simple models like the ecosystem so that we can analyze
our findings without worrying too much about things
that we think will not affect our conclusions to a significant degree.

And so this set of predictable resources can support
exactly 70 Cheetahs in our imaginary territory.

There are many other living creatures and plants in this
territory, some help our cheetahs, some fight it,
some are their food.

But the ecosystem is stable, with stable resources,
and all the other creatures and plants,
like our cheetahs, will keep a stable
quantity.

The animals who are food for the cheetahs will only
replicate so much before the cheetahs eat them,
and so they can feed just those 70 cheetahs and no more.

And so with the food animals,
there will be no more than what the cheetahs
will allow and let live,
and no less, because otherwise they will replicate until there are just enough.

There are seventy cheetahs in the territory today.
Seventy where here 70 years ago.
And also 700 years ago.

Death
The cheetah food always replicates
and dies in the mouths of the cheetahs.

The cheetahs replicate and can never find enough food
for the many replicators, and so most of them also die, of hunger.

All the other animals and plants in the territory replicate.

They all compete with each other on the resources.

Because they keep replicating, the resources are never enough.

A single adult living cheetah is responsible
for the deaths of many food animals.
Many of all creatures die,
most when they are very young.

In The Origin Of Species,
Charles Darwin gives a long and detailed
account of how quickly different animals in Nature would grow
to cover the earth,
if it were not for this high death rate.

Perfection
The cheetah is perfect.

Darwin says perfect means there is nothing that can be better
about it.

Better, meaning, bettering its chances of survival.

If the cheetahs were bettered in any way,
there would be more of them in the territory.

Since they are the same 70 cheetahs
for some millions of years now,
we know they are not better in any way,
and have not changed since a long time ago.

This means that for this environment,
they are perfect,
and so they do not need to change at all.

Darwin calls it: Exactly as perfect as needed.

Variation
Varaiations are the differences between the individual cheetahs.
Since all cheetahs are perfect, they also all look alike.
Cheetah
Cheetah


It is difficult to tell them apart,
because all their qualities are perfect for the territory,
and so they are all almost the same,
among the individual cheetahs.

But they are not exactly the same, ever.

Lets us take an example.

The cheetah is known as the only cat in nature not to be able
to retract its claws. (Nails).

Since we know the cheetahs are nearly perfect in all respects,
they must have all nails of much the same length.
The perfect length nail.

If tomorrow a cheetah is born with a nail slighly longer,
or shorter for that matter,
than this cheetah is not fit to survive in the territory
as well as all the other cheetahs.

Struggle For Existence
Many cheetahs will die young, even if they are perfect.
This cheetah, with the imperfect nail,
will almost surely be one of the many cheetahs
who die young, in their fights
with each other for the food animals in the territory.

All animals and plants always compete with each other
to stay alive.
For the most part, cheetahs fight with cheetahs to see
who
can chase the deer better,
while the deer fight with the other deer to see
who can run away from the cheetahs faster.

It is not a war between the cheetahs and the deer.
Neither side will ever win.
The cheetahs will remain 70,
and likewise the dear will keep their numbers.

This constant undeclared fight among the individual cheetahs
Darwin calls The Struggle For Existence

Mutations
How did this cheetah come about to have such a deformed
fingernail to cause its early death?

Well, lets ignore for the moment the story of the Orangutan.
We will get to him next.

With the perfect cheetahs, the new born cheetahs are supposed to all have the correct fingernails.
Otherwise, how can we say they are perfect?

When mother and father cheetah replicate,
they do not always do an exact job of copying
all the charachters to the baby cheetah.

A mistake in the copying of the plan of the body,
can cause a nail to grow a bit too long or too short.

We call this mistake a Mutation.

New mutations occur all the time.

But since the cheetahs are already perfect,
all mutations are bad for survival,
and so when death comes along,
it will almost always pick up the mutations first.

And death does come along plenty.

This much we have already calculated with us humans and the cockroaches.

Evolution is very effective in exterminating mutations,
and like all else, will select only the very few that are beneficial to their individual owner body.

So for the cheetah for instance,
since the time we called it a Cheetah,
there have been many many mutations with many cheetahs.
None of those survived.

Orangutan
Darwin looked at some orangutans,
and noticed something very odd:

The hands of the individual orangutans are noticibly very
different from one another.

This means that the orangutans can not possibly
all be as perfect as our cheetahs.
If they are so different than one another,
even if just in the shape and length of
their huge hands,
then some orangutans must have better hands than others,
and so they are not all perfect.

Not only that, when father and mother orangutan
replicate a new baby orangutan,
his new hands will also surely be different than all
the others.
After all, his mother and father did not have the same
hands to begin with.

But if the orangutans were ever perfect,
than the struggle for existence would have kept
them perfect.

And so we know,
that they were not perfect to begin with.

In fact, they were probably perfect a long time ago.
perfect for some other territory, or some other climate.
Then, and there,
they were probably like any other
ordinary hands of other apes,
which among the other individuals in the same species,
all look about the same.

Then something happened.
It could be just a change in the territory,
that made the very small differences in the hands
be selected suddenly as better,
and so cause baby orangutans to continue
carrying the genes of hands that are different,
blending with the rest,
creating much variation.

It is also possible that a small chance mutation
was somehow beneficial for survival,
and so it stuck around to the next generation.
Some of the new born Orangutans had some of this
new fine quality, and some not.
Again, there will be high variation.

This is how we came to the present day,
with the hands of the orangutan still imperfect.

Death comes just as quickly, and the better orangutans
with the better hands will survive.

In time, the perfect hands will be selected and remain,
while the lesser hands will disappear.

By then the hands will all look alike.
We will then call the hands of the orangutan perfect again.

Variation and perfection in nature are exact opposites.
The higher the variation, the lower the perfection,
and vice versa.

Natural Selection
Back to our Cheetahs, if a mutation occurs that is good for the cheetah's survival,
there would evolve a slightly better Cheetah.

This new species is likely, and in most cases will,
compete more successfully with the older type Cheetahs in the territory,
on the resources the territory provides.

In time the lesser qualified cheetahs will diminish
in number and slowly disappear, leaving the territory with
just this one new species instead.

We will call this new species a Cheetah,
and say the cheetah has evolved by some small fine quality of survival. Since the lesser cheetah is now extinct,
there should be no reason why we would change its name
in the classification of the animals of Nature.

But if all the while, in another territory, some other cheetahs
linger, and if this territory is sufficiently separate so that
the better cheetahs can not reach it,
then the older species did not become extinct,
and we would need to name the new species,
once we discover that
now there are two of them.

We might call it the long-nailed-cheetah.

This process by which Nature selects
the better replications Darwin calls
Natural Selection.

Evolution
This is why it is believed that Charles Darwin developed most
of his theories during his travel aboard the HMS Beagle,
and in the Falkland Islands and the Galapagos Islands,
where he found many species very much alike other species in
the near continent of South America,
but those species were not present in England
and the rest of Europe in anywhere remotely the same level of
resemblance.

This is the slow process by which new species are created.

Tipycally, it starts with the migration of an individual to
a new territory, or with a gradual change in climate,
or by a single abrupt change in environmental conditions,
later to leave the teritories as stable as before,
with a new set of condition for the contained organisms to
compete over.

Mutations are always there and plentiful.

They don't make evolution happen.

Natural Selection makes evolution happen by selecting
the Right mutations, discarding all others.
